Add capability for typescript type gen to reference table row types

[joeally]

What kind of change does this PR introduce?

Bug fix

What is the current behavior?

In the situation where we have a view in which one of the columns has the row type of a table, unknown is generated for that column.

e.g

CREATE VIEW rows_with_user_view AS (
  SELECT *, users as user FROM rows
  INNER JOIN users on rows.user_id = user.id
);

Currently results in the following generation

{
...
  public: {
    ...
    Views: {
      rows_with_user_view: {
        Row: {
          ...
          user: unknown
        }
      }
    }
    ...
  }
...
}

What is the new behavior?

Instead types should be generated in the following form

{
...
  public: {
    ...
    Views: {
      rows_with_user_view: {
        Row: {
          ...
          user: Database["public"]["Tables"]["users"]["Row"]
        }
      }
    }
    ...
  }
...
}
